I had my iPod plugged in and itunes said that 2.0 was available however the "more info" link was broken. Now the availability of 2.0 has disappeared and iTunes says my iPod is up to date? anyone with the same problem?
That happened to me, but then I clicked the 'check for updates' button a couple times and eventually I got the 2.0 advisory message again. It seems to come and go. Still can't download the upgrade, though.
